MULTIPLE-PLUG STRIP.

SPECIFICATION forming part of Letters Patent No. 519,553, dated May 8, 1894. Application filed September 28,1892. Serial No. 447,174- (No model.)

To aZZ whom it may concern:

Beit known that I, HERBERT G. RoUNDs, a citizen of the United States, residing at West Bay City, county of Bay, State of Michigan, have invented a certain new and useful Improvement in Multiple-Plug Strips; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to a novel article of manufacture in the nature of a multiple plug strip, constructed as hereinafter described and claimed, and illustrated in the accom panying drawings, in which- Figure 1 is aview in perspective of myimproved strip. Fig. 2 is a similar enlarged view of a portion of said strip. Fig. 3 is an end View showing a number of said strips bundled together.

It is obviously a matter of much importance, for the preservation of railway ties, and to make them more durable, to plug up the holes left by the removal of the spikes to keep out the water, and thus prevent the rotting of the ties. To do this it is necessary to provide suitable plugs, to be driven into the spike holes.

My invention is designed to facilitate this work by the provision of multiple plug strips, each strip consisting of two or more plugs in a single integral piece, cut away at suitable intervals, but leaving sufficient integral connection between the adjacent ends of the different plugs, the integral connection therebetween at their joined ends of sufficient strength to permit the handling of the strip Without liability of breakage, and yet allowing the joined ends of two adjacent plugs to be readily separated or broken when one of the plugs is desired to be used. I

Accordingly as shown in the drawings, A represents a multiple plug strip, cut away preferably upon opposite sides as shown at a and a,at suitable intervals to form a series of individual plugs A, said individual plugs having an integral connection at their adjacent ends, as shown at a the opposite sides-of the strip being cut away toward the plugs of the multiple strip, so that it can be' readily handled without breakage, the cut ting away of the strip to form the series of conn acting necks permits the ready breaking 0d of an individual plug whenever one is,

wanted; At the same time, as will be observed, the cutting away of the strip to form the integrally connecting neck forms asharpened point for each plug at one end. The under side of the cut away portion is preferablycut straight into the strip, as shown, so as to form, when an individual plug is separated, a flat driving end. The end of the adjacent plug is preferablycut away on a bevel, as shown, thus-forming a sharpened point thereat,'for entering the hole in the tie.

I do not limit myself to any particular number of the individual plugs forming a multiple strip, as I contemplate, a strip of two or more, but integrally connected as coming within the scope of my invention. It will be convenient however to form a strip with say ten individual plugs, thus integrally joined. These strips may be bound in bundles, so as to be easily shipped and counted. I prefer to make the body of the strip square in cross section. Shaped and connected in this manner the plugs do not need to be boxed for shipment, as they may be conveniently tied in bundles for this purpose, thus dispensing with the expense of boxing them for shipment, as would be required if the plugs were made separate.

What I claim as my invention is 1. As an article of manufacture, a multipleplugstrip, for the purpose described, consisting of a strip of wood, forming individual plugs, united at their adjacent ends by an integral connecting neck, said strip being cut away only at the adjacent ends of said individual plugs on opposite sides, the kerf of the cut away portion on its under side, extending at right angles to the bar to form a flat head on the one plug, when they are disconnected, each kerf at its upper portion constructed on a bevel to form a driving point on the end of the adjacent plug, the main body of each plugremaining of the full size of the original strip, substantially as set forth.

2. As'an article of manufacture, a multipleplug-strip for the purpose described, consisting of a strip of wood of square form in crosssection, cut away at intervals to form individual plugs, united at their adjacent ends by integral connecting necks, the lower portion of the kerf extending into the wood at I5 right angles to the bar to form a flat driving head on the end of one plug, the upper portion'of the kerf constructed in the form of a bevel to form a driving point on the end of the adjacent plug, the main body of each in-- 2o dividual plug remaining of the original form
